Sodium stearate
Question:

Sodium stearate  anionic surfactant which forms micelles in oil.

Choose the correct statement for it from the following :

  1. It forms spherical micelles with $\mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)_{16}-$ group pointing towards the centre of sphere.

  2. It forms non-spherical micelles with $-\mathrm{COO}^{-}$ group pointing outwards on the surface.

  3. It forms spherical micelles with $\mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)_{16}-$ group pointing outwards on the surface of sphere

  4. It forms non-spherical micelles with $\mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)_{16}$-group pointing towards the centre.


Correct Option: 1

Solution:

Forms spherical micelles with $\mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)_{16}$ group pointing towards the centre of sphere
